Systemic Venous Rerouting Through the Coronary Sinus for ccTGA With Bilateral SVCs

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Congenital Heart Disease

Background:

• Congenitally corrected transposition of the great arteries (ccTGA) presents complex surgical challenges.
• The double-switch operation is an effective strategy for restoring left ventricular systemic outflow.
• Persistent left superior vena cava (PLSVC) adds complexity to ccTGA repair.

Observation:

• This case report details a double-switch operation for ccTGA with PLSVC.
• An atrial switch technique was employed without requiring supplemental materials.
• Systemic venous blood flow was successfully rerouted through the enlarged coronary sinus.

Findings:

• The described atrial switch technique offers a viable alternative for ccTGA with PLSVC.
• Successful rerouting of systemic venous return via the coronary sinus was achieved.
• This approach avoids the need for prosthetic materials in the atrial switch component.

Implications:

• This technique may offer a simplified and potentially safer method for complex ccTGA repairs.
• Further investigation into this modified atrial switch for ccTGA with venous anomalies is warranted.
• This approach could improve outcomes for patients with ccTGA and associated venous anomalies.
